  • Rigid tetrazine fluorophore conjugates with fluorogenic properties in the inverse electron demand Diels–Alder reaction
    作者:Achim Wieczorek、Tiago Buckup、Richard Wombacher
    DOI:10.1039/c4ob00245h

    1,2,4,5-Tetrazine fluorophore derivatives with structurally rigid molecular designs were synthesized using Sonogashira and Stille cross-coupling as well as copper-catalyzed azide–alkyne cycloaddition. The synthesized bichromophoric systems exhibit low fluorescence quantum yields due to quenching by the tetrazine. The extent of fluorescence quenching observed for those systems was shown to depend on the distance between the fluorophore and the tetrazine. The decreased fluorescence is “turned on” by conversion of the tetrazine in the inverse electron demand Diels–Alder cycloaddition. Time resolved spectroscopy indicated resonance energy transfer between BODIPY and the tetrazine as the underlying quenching mechanism. The synthesized conjugates were successfully applied in protein labeling experiments.

    Labeling proteins in their natural settings with fluorescent proteins or protein tags often leads to problems. Despite the high specificity, these methods influence the natural functions due to the rather large size of the proteins used. Here we present a two-step labeling procedure for the attachment of various fluorescent probes to a small peptide sequence (13 amino acids) using enzyme-mediated peptide
    用荧光蛋白或蛋白标签在其自然环境中标记蛋白经常会导致问题。尽管具有很高的特异性,但由于所用蛋白质的尺寸较大,这些方法仍会影响自然功能。在这里,我们提出了一个两步的标记程序,使用酶介导的肽标记结合钯催化的Sonogashira交叉偶联,将各种荧光探针连接到一个小的肽序列(13个氨基酸)。我们从一个小文库中鉴定了对碘苯衍生物,该文库可以通过大肠杆菌硫辛酸连接酶A(LplA)共价连接至特定13个氨基酸肽序列中的赖氨酸残基。p的衍生碘代苯基随后在肽以及蛋白质水平上用作生物正交过渡金属催化的Sonogashira交叉偶联与炔基官能化的荧光团的偶联。我们的两步标记策略将酶介导标记的高选择性与钯催化的Sonogashira交叉偶联的化学选择性结合在一起。

Overall, this study demonstrates that cassettes of this kind can label a protein without significantly perturbing its function or secondary structure and they can be visualized effectively via irradiation

  • Cyanine‐ and Rhodamine‐Derived Alkynes for the Selective Targeting of Cancerous Mitochondria through Radical Thiol‐Yne Coupling in Live Cells
    作者:Johannes Köckenberger、Insa Klemt、Caroline Sauer、Anton Arkhypov、Viktor Reshetnikov、Andriy Mokhir、Markus R. Heinrich

    Abstract

    Despite their long history and their synthetic potential underlined by various recent advances, radical thiol‐yne coupling reactions have so far only rarely been exploited for the functionalization of biomolecules, and no examples yet exist for their application in live cells ‐ although natural thiols show widespread occurrence therein. By taking advantage of the particular cellular conditions of mitochondria in cancer cells, we have demonstrated that radical thiol‐yne coupling represents a powerful reaction principle for the selective targeting of these organelles. Within our studies, fluorescently labeled reactive alkyne probes were investigated, for which the fluorescent moiety was chosen to enable both mitochondria accumulation as well as highly sensitive detection. After preliminary studies under cell‐free conditions, the most promising alkyne‐dye conjugates were evaluated in various cellular experiments comprising analysis by flow cytometry and microscopy. All in all, these results pave the way for improved future therapeutic strategies relying on live‐cell compatibility and selectivity among cellular compartments.

    摘要尽管自由基硫醇-炔偶联反应具有悠久的历史,而且最近取得的各种进展也凸显了其合成潜力,但迄今为止,自由基硫醇-炔偶联反应还很少被用于生物大分子的功能化,而且还没有在活细胞中应用的实例--尽管天然硫醇在活细胞中广泛存在。通过利用癌细胞线粒体的特殊细胞条件,我们证明了自由基硫醇-炔偶联是选择性靶向这些细胞器的强大反应原理。在我们的研究中,对荧光标记的活性炔探针进行了研究,荧光分子的选择是为了既能在线粒体中积累,又能进行高灵敏度的检测。在无细胞条件下进行初步研究后,在各种细胞实验中对最有前景的炔烃-染料共轭物进行了评估,包括流式细胞仪和显微镜分析。总之,这些结果为改进未来的治疗策略铺平了道路,这些治疗策略依赖于活细胞兼容性和细胞间的选择性。
